Shrinks are transparent plastic covers used in the shrink-pack machine for packaging and covering. A cut of these transparent layers is placed around the product according to the size of the product that will be sheared. After passing the product through the thermal tunnel of the Shrink Pack machine and cooling it, at the end of the tunnel, these slits are shrunk and contain the product in the form of a pod. In the rest of this article, we will learn more about shrink packaging and its application.

The material of the shrink wrap

Shrink packaging is produced from polyethylene derivatives such as LDPEL and has a thickness of up to 50 microns. When heat is applied to these materials, they acquire the properties of shrinkage and coating and remain in the same state. This heat can be applied by passing through a heating tunnel of the Shrink Pack device or transferring it manually with a torch. The most famous material from which sheeting films are produced is polyolefin, which is suitable for transparency, strength, and shrinkage. Other materials from which shrink rolls are made include:

Shrinks are PVC, Polyethylene, and Polypropylene. Some of these materials are suitable for industry, and others are suitable for food and medicine. Depending on the application, these rolls can be produced in one or more layers and have different degrees of transparency. Apart from the transparent nylons of Shrink mentioned above, enrollments have been created with various symbols and inscriptions. These rolls are sheeted and pasted on the product with the help of a machine, and they no longer have the simplicity and uniformity of single-color transparent rolls; this type of sheeting is called a slow sheeting label.

Shrinking labels are used in a wide range of products today, and it is rare to see plastic boxes and bottles that still need to have a Shrink Slow label printed on them. The material of these labels can be made of materials such as PETG, OPS, and K resin. Their most common material is polyvinyl chloride, which, while available, is cheaper than other materials.

The use of shrink wrap

Each product must be packaged in its way, depending on what it is and in what category it is placed. Packaging fresh food, bulk products, chemicals, drugs, medical equipment, bottles of soft drinks and mineral water, biscuits and chocolate, etc., is different.

With the help of shrinkage, several products that are unstable in terms of balance can be packaged together. Plastic is a good insulator for moisture; shrinking can prevent moisture from entering the product.

Shrink, unlike cardboard and cardboard packaging, is a transparent cover where the product’s appearance is easily visible.

Shrink is the only suitable option for products that display the size and shape of the product and must be placed inside a thin cover.

Shrink packaging machine

As you know, this type of plastic is packaged using heat, so you can use the following methods to use shrink pack, which are:

Manual packing is done using an industrial hair dryer and human power.

Packaging can be done with different machines, such as tunnel shrink machines, cabinets, or other machines, which can be purchased in the market in different brands, volumes, heat levels, and applications.

Shrink design and printing

Today, one of the critical and influential factors in increasing product sales is proper packaging with eye-catching design and quality printing.

The types of printing methods are:

Heliogravure printing uses a cast-iron metal plate, which has an unlimited lifespan, and there is no need to replace the plate until the design is changed. This printing method is specially designed for flexible cellophane or polypropylene films, which provides the customer with excellent high quality and clarity.

Flexo printing can print on all kinds of polymer and paper materials. Still, it is mainly used for polymer films such as polypropylene and especially polyethylene.

This printing method is the best choice for nylon or LDPE shrinks.

The cost of printing on plastic sheeting depends on your design or image and the number of colors used, so it is only possible to announce the price once you see the design, image, or logo.

Advantages of shrink wrap

Shrink products have many advantages. These benefits are so significant that, in many cases, shared packaging has become the first choice of manufacturers and business owners. Some of the advantages of thermal shrink wrap are:

Environmentally friendly

Prevent water penetration

Prevent dust penetration

Preventing the penetration of bacteria and viruses

Maintaining the freshness of food products

Maintaining the health and heat of food prepared in restaurants

Removing excess space and compacting the product

Prevent physical damage to the product

The possibility of packaging all kinds of products

Other essential points for shrink packaging

Do not stack shrink rolls because if they are left unused for a long time, the cardboard tube inside them will deform. If the cardboard tubes inside them change their shape, using the roll inside the device will be challenging. So take care of them properly. Another tip to protect the cardboard is to keep the rolls from moisture.

Please do not press the nylon rolls or place them vertically because, over time, the nylons will slide and be challenging to use; using a conical roll will cause insufficient product packaging. So keep them horizontal. Be careful with the machine’s heat so the nylon does not melt or burn. The lifespan of shingles will decrease over time in sunlight, so keep them out of the sun.
